Cooking measurement converter
Convert between cups, tablespoons, teaspoons, grams, ounces, and milliliters. Weight↔volume conversions use the density of the ingredient you pick, so a cup of flour and a cup of honey give different — and correct — answers.
Cooking conversions may vary depending on ingredient density, packing method, and regional cup size.
Ingredient weights per cup
The densities behind this converter, stated as the weight of one US cup (236.588 mL). Values follow USDA FoodData Central and standard baking references; spoon-and-level flour rather than scooping.

| All-purpose flour | 125 g | 4.4 oz | 0.528 |
| Bread flour | 130 g | 4.6 oz | 0.549 |

Frequently asked questions
Why does converting cups to grams need an ingredient?
A cup measures volume, a gram measures weight, and the bridge between them is density. A cup of honey weighs about 339 g while a cup of flour weighs about 125 g, so no single factor can convert cups to grams for every ingredient.
How many grams is one cup of all-purpose flour?
One US cup of spooned-and-leveled all-purpose flour weighs about 125 grams. Scooping the cup directly into the flour bag compacts it and can add 20–30 grams, which is why bakers prefer weighing.
What is the difference between a US, metric, and imperial cup?
A US cup is 236.588 mL (half a US pint), a metric cup used in Australia and New Zealand is exactly 250 mL, and the older imperial cup is 284.131 mL (half an imperial pint). Recipes rarely say which one they mean, so check the recipe's origin.
Are teaspoon and tablespoon conversions exact?
Volume-to-volume conversions are exact: a US tablespoon is exactly 3 teaspoons (14.7868 mL) and a US cup is exactly 16 tablespoons. Only conversions that cross between weight and volume depend on the ingredient and are approximate.
